Polishing and Coating of Laser Crystals and Glasses

  • Polishing and Coating of a Wide Variety of Crystals and Laser Glasses

  • Round, Rectangular, and Zigzag Form Factors Available

  • High Laser-Induced Damage Threshold (LIDT) Coatings


Edmund Optics® is an industry leader in laser crystal and glass polishing and coating. Our Florida facility works with a wide variety of materials including YAG, YLF, YALO, KTP, LBO, BBO, YVO4, PPSLT, PPLN, and phosphate-doped glasses. Our precision polishing processes improve coating adhesion, minimizing losses and increasing LIDT.

Laser crystal and doped glass slabs are some of the most popular gain media in solid-state laser sources. They are often doped with transition metal or rare earth ions that amplify input laser light through stimulated emission. Non-linear crystals are used for frequency conversion of laser sources. Laser crystals benefit from less absorption, a narrower emission bandwidth, higher transition cross sections, and higher thermal conductivity compared to doped glasses and other gain media. What can we make for you?


Our expert manufacturers are skilled at planning for optimal material usage throughout cutting, polishing, and coating.
